EMBEDDED
PLC BL2500 User’s Manual Introduction
OEM Technology Solutions Page 2
Table 1: Main Features of the
EMBEDDED
PLC Firmware Kernel V1.04 on the BL2500
Kernel filename BL2500C_V1.04_3-0231H.bin
SBC model supported BL2500 with Rabbit core module RCM3200 (10/100BaseT, 512K Flash, 256K +
512K SRAM, 44.2 MHz clock speed). Z-World P/N: 101-0602
I/Os supported - 16 Digital Inputs
- 8 Digital Outputs
- 1 Analog Input (connected through AD0): 10 bits resolution, 0 – 3.3 V
- 1 Analog Output (connected through DA1): 10 bits resolution, 0 – 3.3 V
Communications Modbus RTU over TCP/IP using static IP address
Modbus RTU over RS232 (using serial port E) or RS485 (using serial port D):
- Baud rate: 19200, 9600, 4800, 2400, 1200 or 600 (configurable through
EMBEDDED
PLC Utility)
- Parity: None
- Data bits: 8
- Stop bits: 1
- Flow Control: None
Minimum polling period time is 1 cycle duration for Modbus TCP and 2 x cycle
duration for Modbus RTU over RS232/RS485. Cycle duration corresponds to the
time that kernel executes one cycle (read inputs
→
execute logic
→
update
outputs)
Performance
- Digital Input scan time is approx. 200 µs.
- Analog Input scan time is approx. 83 ms.
- Digital Output update time is approx. 30 µs per output.
- Analog Output update time is approx. 120 µs.
- Boolean instruction execution time is approx. 30 µs.
- Program execution overhead is approx. 100 µs per program.
Memory Space Maximum size of ISaGRAF application database is 50000 bytes.
Size of ISaGRAF real-time database (holds variables, SFC engine data, C function
and function blocks data) is 10000 bytes.
Free root memory on the BL2500 is approx. 9000 bytes.
EMBEDDED
PLC firmware kernel total code size is approx. 260000 bytes.
ISaGRAF V3.50 features
not supported by
EMBEDDED
PLC
- On-line modifications. This feature enables the user to modify the application
while the process is running.
- Uploading application stored in the target.
